Hi Henrik
The NCV feature in Xymon is fantastic, and I love it. It's a quick and easy way to populate a graph with data. My problem with it, is it sometimes works too well. Sometimes, we have output that contains : or = that's not part of the graphing data, and if you are using SPLIT_NCV, it dutifully tries to graph this information, often with woeful results. I am looking for a feature that we can use to tag a line as "NCV leave this alone!" Perhaps a string of hidden characters at the end of a line, or even a string of visible characters, which the display process can strip out.

Alternatively, a method to mark a section as NCV data, so that other extraneous data are not misinterpreted. Could be escaped in markup to avoid being rendered, like so:
last update at 10:43:16 <!-- ---NCV-BEGIN--- --> apples: 3 oranges: 7 <!-- ---NCV-END--- --> date of update: 2014/4/1

One of my scripts had something like
OUTPUT="$(echo "${OUTPUT}"|sed -e 's/:/\:/g')" to convert all the colons I wanted to hide to the corresponding entity name, which wouldn't cause that problem. (OUTPUT would be concatenated with the graphing data later in the script) Replacing = too would just mean adding to the sed command: -e 's/=/\=/g'

I also like the ease of use of the NCV feature. Most of the times I hand over the values as hidden html comment in my test page:
<!-- Begin Xymon NCV section name1:value1 name2:value2 end Xymon NCV section -->
Then I'm able to separate the more verbose human readable test output from the NCV name value pairs. This works like a charm, but sometimes Xymon gets confused if there are ":" or "=" in the text output (like in date strings...).
What I would suggest is to extend the NCV feature to only grab such lines with a special keyword like this:
name1:value1 NCVDATA or name1:value1 <!-- NCVDATA -->
Then Xymon need only to look for lines with the keyword NCVDATA. (or maybe it is easier to create a second NCV type to keep backwards compatability).

<!-- Begin Xymon NCV section name1:value1 name2:value2 end Xymon NCV section --> Perhaps it is good to mention an alternative for NCV, which is the DEVMON format. For example, if a status message contains the following snippet:
<!--DEVMON RRD: NameA 0 0 DS:DsA:GAUGE:600:0:U DS:DsB:GAUGE:600:0:U NameB ValueA:ValueB -->
xymon will create an RRD named NameA.NameB.rrd containing two DS's. I use it often in stead of NCV.
